[0040] Reference Figures 1-2 As shown in Figure 9, this utility model provides a technical solution: an installation assembly for installing corner protectors 1, including a suction mechanism 10 and a bidirectional moving device 20; the suction mechanism 10 includes a suction component 11, the suction component 11 includes a support plate 111 and a plurality of suction cups 112, the plurality of suction cups 112 are all disposed on the support plate 111; the output end of the bidirectional moving device 20 is connected to the side of the support plate 111 away from the plurality of suction cups 112.

[0041] For example, all the suction cups 112 can be arranged in an array. The bidirectional moving device 20 can be a bidirectional truss platform, etc.

[0042] In this embodiment, when picking up the corner protector 1, the bidirectional moving device 20 moves the suction mechanism 10 to the corner protector fixture and uses the suction cup 112 to pick up the corner protector 1. When installing the corner protector 1, as the bidirectional moving device 20 moves the corner protector 1 to the position of the product to be packaged, the bidirectional moving device 20 pushes the suction mechanism 10 toward the product to be packaged, installing the corner protector 1 onto the corner of the product to achieve packaging of the corner of the product. This allows for automatic installation of the corner protector 1 without manual intervention, thereby improving work efficiency and reducing the labor intensity of operators.

[0043] Reference Figure 2As shown, in some embodiments, the suction assembly 11 includes a protective plate 113 connected to the support plate 111. The protective plate 113 has a second through hole 1131 for each suction cup 112. The suction end of the suction cup 112 passes through the second through hole 1131 and is exposed outside the protective plate 113.

[0044] For example, all suction cups 112 can be divided into at least two suction cup groups. There can be at least two protective plates 113, with each protective plate 113 corresponding to one suction cup group.

[0045] In this embodiment, the guard plate 113 can increase the contact area with the corner protector 1, thereby preventing the corner protector 1 from falling off.

[0046] Reference Figure 2 As shown, in some embodiments, the suction mechanism 10 includes a back plate 12 and a vibration damping component 13. The back plate 12 is connected to the output end of the bidirectional moving device 20, and the support plate 111 is connected to the back plate 12 through the vibration damping component 13.

[0048] In this embodiment, when the bidirectional moving device 20 drives the suction assembly 11 to move, the support plate 111 may be affected by vibration and move in the vertical direction. The vibration is offset by the vibration damping assembly 13 to avoid the support plate 111 from moving too much and to prevent the corner guard 1 from falling off.

[0049] Reference Figures 2-3 As shown, in some embodiments, the support plate 111 has a first through hole 1111. The vibration damping component 13 includes a support base 131, a connecting rod 132, a fixed base 133, and two elastic elements 134. The connecting rod 132 is movably disposed on the support base 131. One end of the support base 131 away from the connecting rod 132 passes through the first through hole 1111 and is connected to the back plate 12. Both ends of the connecting rod 132 are connected to the support plate 111 through the fixed base 133. The elastic elements 134 are correspondingly disposed between the fixed base 133 and the support base 131.

[0050] For example, the elastic element 134 can be a spring or an elastic rubber ring, etc.

[0051] In this embodiment, when the support plate 111 moves vertically due to vibration, the fixed seat 133 can compress the elastic element 134 to deform in order to counteract the vibration and thus reduce the vibration of the support plate 111.

[0052] Reference Figures 2-3As shown, in some embodiments, the suction mechanism 10 includes a first detection element, which is disposed on the support plate 111, with the detection end of the first detection element facing the suction cup 112.

[0055] Reference Figure 1 and 4 As shown in ~9, in some embodiments, the bidirectional moving device 20 includes a first moving mechanism 21 and a second moving mechanism 22. The second moving mechanism 22 is connected to the output end of the first moving mechanism 21, and the output end of the second moving mechanism 22 is connected to the side of the back plate 12 away from the support plate 111.

[0056] For example, the first moving mechanism 21 can be a conveyor or the like.

[0057] In this embodiment, the first moving mechanism 21 can drive the suction component 11 to move toward or away from the corner protector fixture, or to move toward or away from the packaged product, and the second moving mechanism 22 can drive the suction component 11 to switch back and forth between the position of the corner protector fixture and the packaged product.

[0058] Reference Figure 1 and 4 As shown, in some embodiments, the first moving mechanism 21 includes at least two third sliding members 211, a first support plate 212 and a first driving member 213. The first support plate 212 is disposed on the at least two third sliding members 211, and the output end of the first driving member 213 is connected to the first support plate 212.

[0060] In this embodiment, the first driving member 213 provides power to drive the first carrier plate 212 to move through the third sliding member 211, so as to drive the suction assembly 11 to move toward or away from the corner protector fixture, or toward or away from the packaged product.

[0061] Reference Figure 1 and 9 As shown, in some embodiments, the first moving mechanism 21 includes a second detection element 214, which is disposed between two third sliding elements 211 and is located near the corner guard fixture.

[0062] For example, the second detection element 214 can be a photoelectric sensor, etc.

[0063] In this embodiment, the second detection element 214 performs positioning detection on the first bearing plate 212, thereby facilitating the removal of the corner protector 1.

[0064] Reference Figures 4-7 As shown, in some embodiments, the second moving mechanism 22 includes a support member 221 and a first moving component 222. The first moving component 222 includes a first moving plate 2221 and a second driving member 2222. The first moving plate 2221 is connected to the support member 221 through at least two fourth sliding members 22211. The second driving member 2222 is disposed on the support member 221, and the output end of the second driving member 2222 is connected to the first moving plate 2221. The first moving plate 2221 is connected to the side of the back plate 12 opposite to the support plate 111.

[0065] For example, the support member 221 can be a support frame, etc. The second drive member 2222 can be a cylinder or a hydraulic cylinder, etc. Alternatively, the first drive member 213 can include a motor, a lead screw, and a nut seat, etc.; wherein the support member 221 has a first wall surface 2211 and a second wall surface 2212, the first drive member 213 is disposed on the second wall surface 2212, the support member 221 has a third through hole 2213 extending from the first wall surface 2211 toward the second wall surface 2212 and penetrating the second wall surface 2212, and one end of the nut seat passes through the third through hole 2213 and is connected to the first moving plate 2221. Alternatively, the first drive member 213 can include a motor, a synchronous belt, and two synchronous pulleys, etc. Alternatively, the first drive member 213 can include a motor, a chain, and two gears, etc.

[0066] In this embodiment, the second driving member 2222 provides power, which can drive the first moving plate 2221 to move through the fourth sliding member 22211, so as to realize the switching of the position of the driving suction assembly 11 between the corner guard fixture and the packaged product.

[0067] Reference Figures 4-7As shown, in some embodiments, the first moving plate 2221 has a fourth through hole 22212. The second moving mechanism 22 includes a second moving component 223, which includes a transmission member 2231, a first connecting plate 2232, a second connecting plate 2233, and a second moving plate 2234. The transmission member 2231 is disposed on the first moving plate 2221 and corresponds to the fourth through hole 22212. The transmission member 2231 is connected to the support member 221 through the first connecting plate 2232 and to the second moving plate 2234 through the second connecting plate 2233. The second moving plate 2234 is connected to the first moving plate 2221 through at least two fifth sliding members 22341 and to the side of the back plate 12 away from the support plate 111.

[0068] For example, the transmission component 2231 may include a timing belt and two timing pulleys, etc.; wherein the first connecting plate 2232 and the second connecting plate 2233 are both disposed on the timing belt. Alternatively, the transmission component 2231 may include a chain and two gears, etc., wherein the first connecting plate 2232 and the second connecting plate 2233 are both disposed on the chain.

[0069] Reference Figures 7-8 As shown, in this embodiment, when the first moving plate 2221 moves, it drives the second moving plate 2234 to move via the transmission member 2231. By making the stroke of the second moving plate 2234 greater than that of the first moving plate 2221, the stroke of the suction assembly 11 can be increased.

[0070] Taking the transmission component 2231, which includes a synchronous belt and two synchronous pulleys, as an example, since the synchronous belt is fixed to the first wall surface 2211 via the first connecting plate 2232, when the first moving plate 2221 moves toward the product being packaged, the first connecting plate 2232 is stationary, generating a pulling force on the synchronous belt, causing the synchronous belt to move counterclockwise and driving the two synchronous pulleys to rotate. Simultaneously, since the second connecting plate 2233 is misaligned with the first connecting plate 2232, the synchronous belt generates a pulling force on the second moving plate 2234 via the second connecting plate 2233, causing the second moving plate 2234 to also move toward the product being packaged.

[0071] Reference Figures 7-8As shown, in some embodiments, the second moving mechanism 22 includes a third moving component 224, which includes a second support plate 2241, a third driving member 2242, and a connecting seat 2243. The second support plate 2241 is movably disposed on the support member 221 and is connected to the second moving plate 2234. The third driving member 2242 is disposed on the second support plate 2241, and the connecting seat 2243 is connected to the output end of the third driving member 2242. The suction mechanism 10 has two components, which are divided into a first suction mechanism and a second suction mechanism. The connecting seat 2243 is connected to the side of the back plate 12 of the second suction mechanism away from the support plate 111. The back plate 12 of the second suction mechanism is connected to the second moving plate 2234 through at least two second sliding members 121.

[0072] For example, the third drive component 2242 can be a cylinder or a hydraulic cylinder, etc. Alternatively, the first drive component 213 can include a motor, a lead screw, and a nut seat, etc. Alternatively, the first drive component 213 can include a motor, a timing belt, and two timing pulleys, etc. Alternatively, the first drive component 213 can include a motor, a chain, and two gears, etc.

[0073] In this embodiment, the third driving member 2242 provides power to the second suction mechanism through the connecting seat 2243, driving the second suction mechanism to move. This allows adjustment of the distance between the second and first suction mechanisms to accommodate the specifications of the corner protector fixture and the packaged product. Furthermore, when the second moving plate 2241 moves, it can drive the second supporting plate 2241 to move accordingly, thereby preventing interference between the back plate 12 of the second suction mechanism and the connecting seat 2243.
